Well I’m happy that v5.windowsupdate works for GreenBrowser, when it changed from v4 to v5 I couldn’t access it with Avant (an IE core based browser). This could have been early days with v5 as since your post I have checked it again and it now works.

This however, doesn’t negate any of the other points on being forced to use IE, since it’s an integral part of the windows xp system, you can’t not use and you have to keep it up to date.
